TriStar Arms Cobra Iii Marine 3" 5-Round Pump-Action Shotgun

The TriStar Arms Cobra III Marine 3" 5-Round Pump-Action Shotgun is purpose-built for close-quarters tactical operations, home defense, and marine environments where corrosion resistance and fast target engagement are non-negotiable. This 37.7-inch shotgun weighs 7.88 lbs, delivering the rapid-fire capability demanded by law enforcement and military applications without sacrificing control or accuracy. The 5-round capacity paired with a 3-inch chamber provides sufficient firepower for dynamic entry scenarios while maintaining the reliability that professionals depend on.

Built on a proven pump-action operating system, the Cobra III Marine features marine-grade corrosion treatment designed to withstand saltwater exposure and harsh field conditions—critical for coastal and amphibious operations. The 3-inch chamber accepts both 2.75-inch and 3-inch rounds, offering tactical flexibility in ammunition selection without requiring platform swaps. Pump-action operation ensures mechanical reliability independent of ammunition type or shooter technique, making this shotgun a trusted choice where semi-automatic dependency is unacceptable. The compact 3-inch barrel configuration reduces overall length for vehicle storage, room-clearing drills, and confined-space deployment.

Law enforcement tactical teams, military personnel, and civilian operators preparing for home defense benefit most from this shotgun's combination of stopping power and operational durability. The marine-grade finish extends service life in humid climates and corrosive environments where standard bluing breaks down rapidly. Standard 12-gauge shotgun accessories—tactical slings, extended magazines, and aftermarket stocks—integrate seamlessly, allowing operators to configure the Cobra III to mission-specific requirements. Whether deployed in breach operations, perimeter security, or rapid-response scenarios, this pump-action platform delivers the reliability and performance standards that tactical professionals demand.
